The invention relates to the technical flied of a medical instrument, and especially relates to an abutment-teeth preparation adjacent-teeth proximal face protective device. The protective device comprises a moulding sheet, an end part at one side of the moulding sheet and one end of a metal wire are fixedly arranged, several fixed slots are uniformly arranged at an outer rim at the upper end of the end part of the opposite side of the moulding sheet at intervals, the fixed slots are used for binding and fixing the other end of the metal wire, a part between two ends of the metal wire passes through a screw, a cannula is sleeved at the outer rim of the screw, and an internal screw thread arranged at an inner rim of the cannula is matched with an external screw thread arranged at the outerrim of the screw; and a transverse plane outside the cannula employs a flexible material.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a face protection device for abutment preparation and adjacent teeth. Background technique [0002] In dentistry for fixed restoration or single crown restoration, abutment tooth preparation must be carried out first, and for some inexperienced doctors or posterior teeth that are not easy to prepare, the process of preparing the adjacent surface at high speed is likely to cause wear of the adjacent teeth and damage the abutment The normal contact relationship between the patient and the patient will cause pain or even secondary injury to the patient. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a kind of abutment tooth preparation adjacent tooth facing protection device which is reasonable in structure, convenient to fix, and can effectively prevent adjacent teeth from being damaged....
